Mobile Electroencephalography (mEEG)

Electroencephalography (EEG) is a non-invasive method to record the electrical brain activity of people by placing electrodes on their scalp. These recordings can offer insights into a person's cognitive processes and cognitive load.

The GIVA research group has a mobile LiveAmp 64, an EEG system that records 64 referential channels with active electrodes. With the LiveAmp 64, the EEG system can be used in the lab or outdoors—without mobility restrictions—to obtain high-density electrical brain activity data.

LiveAmp 64

• LiveAmp 64 dimensions (W x D x H): 140 mm x 83 mm x 18 mm (incl. connectors: 25 mm), and approximately 120 g in weight (incl. built-in battery)
• Active actiCAP electrodes
• Built-in trigger/marker input
• 250 Hz, 500 Hz, and 1000 Hz sampling rate
• Built-in 3-axis acceleration sensor with three separate channels (x, y, z)
• Up to 500 kOhm impedance measurement range
• Data storage on recording computer via wireless transmission, micro memory card (32 GB Micro SD card), or both.
• Wireless transmission range of up to 10 m for indoor and up to 30 m for outdoor environment
• Built-in rechargeable battery with 1000 mAh capacity
• Uninterrupted recording time with built-in battery (when fully charged) up to 3 hours for wireless data transfer and 4.5 hours when stored on memory card
• The BrainVision Recorder software is used to control the LiveAmp 64 for experimental setup, connecting, setting the impedance level and displaying the topographic head map with impedance levels, recording, and real-time display and saving of continuous EEG- and psychophysiological data
